[PATCH 0/7] multipath-tools: uevent processing fixes and unit tests

[Martin Wilck <mwilck@suse.com>]

Hi Christophe,

The incentive for creating this series was Ritika's patch "multipath-tools:
Skip CHANGE uevent for non-mpath devices" from October 2017, plus the
observation that uevent.c contains a lot of code repetition.
I've refactored and simplified the uevent_get_XXX code, and started to use
"const" qualifiers in the part of the code which I touched in the process.

In order to avoid regressions in the process, I took this as a starting point
for implementing a simple unit test framework. For now, it covers only the
stuff that I changed in this series.

The series is based on my previous patch series ("Various 
multipath-tools fixes"), v2. The first patch doesn't belong in the series
logically, but I thought it may help you track the ordering if I include it
here rather then posting separately or spamming the list with the big series
again.

Regards,
Martin
